Apple on Wednesday released Safari 8.0.6, a minor update of the Mac browser, concentrating primarily on fixing security holes discovered in the software.

The v8.0.6 release requires OS X Yosemite. Apple has simultaneously released Safari 7.1.6 for OS X Mavericks, and v6.2.6 for Mountain Lion, both of which share the same focus.

Release notes for the updates indicate that the vulnerabilities are all found in WebKit, the rendering engine underlying Safari. One would allow a malicious website to cause a crash or hijack a system, while another would let a site access filesystem contents. A third would let a site spoof the user interface.

Each of the Safari updates can be downloaded via the Updates tab at the Mac App Store.
